PHP 8 Programming Tips, Tricks and Best Practices

By: Doug Bierer

Overview of this book

Thanks to its ease of use, PHP is a highly popular programming language used on over 78% of all web servers connected to the Internet. PHP 8 Programming Tips, Tricks, and Best Practices will help you to get up-to-speed with PHP 8 quickly. The book is intended for any PHP developer who wants to become familiar with the cool new features available in PHP 8, and covers areas where developers might experience backward compatibility issues with their existing code after a PHP 8 update. The book thoroughly explores best practices, and highlights ways in which PHP 8 enforces these practices in a much more rigorous fashion than its earlier versions. You'll start by exploring new PHP 8 features in the area of object-oriented programming (OOP), followed by enhancements at the procedural level. You'll then learn about potential backward compatible breaks and discover best practices for improving performance. The last chapter of the book gives you insights into PHP async, a revolutionary new way of programming, by providing detailed coverage and examples of asynchronous programming using the Swoole extension and Fibers. By the end of this PHP book, you'll not only have mastered the new features, but you'll also know exactly what to watch out for when migrating older PHP applications to PHP 8.

In this chapter, you learned about the FFI, its history, and how it can be used to facilitate rapid PHP extension prototyping. You also learned that although the FFI extension should not be used to improve speed, it also serves the purpose of allowing your PHP application to directly call native C functions from an external C library. The power of this ability was demonstrated through an example that called a bubble-sort function from an external C library. This same capability can be extended to encompass any of the thousands of C libraries available, including machine learning, optical character recognition, communications, encryption; ad infinitum.

In this chapter, you acquired a deeper understanding of how PHP itself operates at the C- language level. You learned how to create and directly use C-language data structures, giving you the ability to interact, and even override, the PHP language itself. In addition, you now have an idea how to incorporate the functionality...
